In this edition of the Threat Source newsletter, William reflects on the “Make Hazel a Hacker” segment in Beers with Talos, and how cybersecurity is a field where questions can lead to multiple correct answers.

Cisco Talos recently identified an undocumented phishing framework, internally branded "JWR" by its developer, built to convincingly impersonate checkout and login pages across major payment and shopping platforms.

Microsoft has released its monthly security update for August 2026, which includes 421 vulnerabilities affecting a range of products, including 62 that Microsoft marked as "critical."

I’ve successfully survived Hacker Summer Camp, and I have returned with a new outlook on patch density. When even Linus Torvalds says that huge updates are the “ new normal ”, it’s time to readjust what we consider a true bug apocalypse. This month’s release is thankfully smaller than last months...

Every Signal chat starts the same way: the client asks the Signal server for the public key associated with your contact’s phone number. But how do you know the server gave you the right key? A compromised server could provide a false public key, allowing the client to encrypt messages to an atta...

Analysis of the Aeternum botnet loader, a threat leveraging Polygon blockchain smart contracts for decentralized C2 infrastructure and payload execution. The post The Permanent Threat: Analyzing Aeternum’s Blockchain-Based C2 Operations and Communications appeared first on Unit 42 .

Identity-based attacks drive 90% of incidents. Learn how modern attackers exploit identities and what SOC leaders can do to respond. The post Inside the Modern SOC: The Identity Front Door appeared first on Unit 42 .

Gareth Heyes - gareth.heyes@portswigger.net - @garethheyes It's quite common for webmail clients to render untrusted CSS in a trusted UI. They attempt to make this safe using CSS sanitization. In this

Abstract In this paper we’ll show that HTTP Header Injection is severely underestimated. Forget open redirects or Cross-Site Scripting and instead, embrace the catastrophic potential of the CRLF-Power

Abstract We all know AI can find bugs. After a decade of research, I asked a harder question: can an autonomous system invent new attack techniques, and use them to hack live websites at scale? Buildi

Nitro Enclaves and Key Management Service (KMS) feel like a natural fit: since the KMS can verify attestation documents generated by the enclaves, developers can offload key management tasks from their applications to the AWS-managed service. But integrating an external service with your trusted ...

Welcome to our monthly look at Apple security patches. This release shows that Apple is not immune to the bug apocalypse that is impacting other vendors. Last month, they released 37 unique CVEs compare to this month’s 210. Quite a jump. For July 2026, Apple released 210 unique CVEs across iOS/iP...

Uniswap v4 hooks let developers add custom behavior to pools, including dynamic fees, custom accounting, and external integrations. This flexibility moves some security responsibilities into application and hook code. The Cork and Bunni exploits are two app-level incidents that show what can go w...

If you just want to read the rules, you can find them here . Pwn2Own Ireland returns for 2026, and it’s the third year for this event in the Emerald Isle. Despite the dreary Irish skies (and the threat of a random banshee ), we had an amazing event, even if we did end up in a jail at the end. Wit...

We recently published an exploit chain for the Google Pixel 9 that demonstrated it was possible to go from a zero-click context to root on Android in just two exploits. The Dolby 0-click vulnerability existed across all of Android, until it was patched in January 2026. While we had an exploit cha...

Mutational grammar fuzzing is a fuzzing technique in which the fuzzer uses a predefined grammar that describes the structure of the samples. When a sample gets mutated, the mutations happen in such a way that any resulting samples still adhere to the grammar rules, thus the structure of the sampl...

In my previous blog post I mentioned the GetProcessHandleFromHwnd API. This was an API I didn’t know existed until I found a publicly disclosed UAC bypass using the Quick Assist UI Access application. This API looked interesting so I thought I should take a closer look. I typically start by readi...
